HIGKOKMANUFACTURING COMPANY, or HARRISBURG, PENNSYLVANIA, A CORPORATION OFPENNSYLVANIA PEN FOB RULING MACHINES Application filed November 7, 1929.Serial No. 405,504.

In certain modern ruling machines which are operable at high speed,difficulty has been experienced in striking due to the spatter ing ofthe ink from the pens. This to some extent is due to the vibration orshivering of the pen because of its quick lifting and droppingmovements.

One of the objects of the present invention is to provide a penstructure that is stiffer at the place where the pen is bent between theshank or back and the point, which place is the weakest, the stiffeningmeans thereby preventing the shivering or vibration of the point duringthe vertical swinging movements thereof and also incidentally acting asan additional anchoring means that prevents lateral displacement of thepen in the pen holder or carrier.

In the embodiment disclosed:

Figure 1 is a cross sectional view through a modern form of pen beamshowing a pen therein, the pen being illustrated in longitudinalsection.

Figure 2 is a front elevation of the structure illustrated in Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Figure 4 is a plan view of the pen.

Figure 5 is a perspective view of the same.

Figure 6 is a side elevation of said pen.

Figure 7 is a top plan view of a modified form of construction.

Figure 8 is a perspective view of the pen shown in Figure 7 Consideringthe embodiment disclosed in Figures 16 inclusive, the pen is formed of astrip of sheet metal and comprises a flat relatively wide shank 9 withthe usual narrower point portion or bowl 10. This shank portion isprovided with a bend 11 so that the bow or point portion 10 is disposedat an angle to the shank portion 9. The point portion has its side wallsbent upwardly to form a channel 12 and in the present embodiment thischannel is extended through the ofiset part 13 of the shank 9 andlongitudinally into said shank, so that an extension 14 of the channelbridges the bend 11 of the shank. As a consequence the bend or angle ismaterially stiffened so that when the pen is mountpen is clampedclamped, as clearly shown in Figures 1 and 3, the rib 16 will be beddedin the cushions 19 and consequently the pen will be held against lateraldisplacement.

In Figures 7 and 8 the structure is substantially the same as that abovedescribed except that the channel is extended substantially the fulllength of the shank. Thus the shank in these figures is designated 9aand the point or bowl member 106;. The channel is illustrated at 14a andas shown bridges the bend 11a. The advantages are the same in this formof structure as in that first described.

It will be evident that this device, while simple in construction, hasdecided advantages over that usually employed in which the shank at thebond is flat so that it constitutes a relatively weak line on which thepen point vibrates vertically. Preferably in the formation of thestructure the groove or channel 1t-1-ata is formed after the bend11-1101. has been made, it being found that this produces a strongerstructure.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art without further description and it will beunderstood that various changes in the size, shape, proportion andminordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

What I claim, is:

A pen for ruling machines, comprising a sheet metal strip having a broadsubstantially flat shank portion and a narrower bowl or point portiondisposed at an obtuse angle to the shank portion and having its upperside longitudinally channeled, the channel of the bowl or point portionextending into the upper side of the shank portion and forming a rib onthe underside of said shank portion- 101 interlocking Wlthtlle materialof the pen earn.

In testimony whereof, I afliX my signature.

ALBERT BROADMEYER.
